Introduction 11 Willamette Park Redevelopment and Phasing Plan

History

The Willamette River was a travel route for generations of native peoples and it is likely that Clackamas tribal gatherings took place in the area where Willamette Park is now located. A trail along the riverbank would have passed near the park.

Early homesteading maps show that the rich soil of the frequently-flooded park area was farmed as early as 1852 by Thomas Stephens, who occupied a cabin on the riverbank.

The South Portland area adjacent to Willamette Park initially developed as the town of Fulton and when the Portland & Willamette Valley Railroad opened their rail line along the west bank in 1887, rapid development in Fulton began. 1939 park aerial photo

The 1904 Portland Park Plan by John Charles Olmsted recommended a riverfront park on this location, to be called North Fulton Park. The plan noted: North of Fulton, in the southern part of the city, between the railroad and the river, is a beautiful stretch of low but undulating grassy land, well furnished with broad-spreading deciduous trees, among them the oak (which is decidedly rare elsewhere in the city) which would be a most desirable site for a local park and play ground…

The Olmsted Park Plan has shaped the city’s system of parks and open space, although the idea of a North Fulton Park was not immediately implemented due to lack of funds and political will. The neighborhood continued to develop rapidly and many commercial 1852 map of the Willamette Park area and industrial businesses grew in the neighborhood adjacent to the park.

12 Introduction Willamette Park Redevelopment and Phasing Plan

Recognizing the need to act before the park site was developed, the City of Portland acquired part of the land in 1926, but few improvements were made initially. More park land was acquired in 1942. In the 1960s and 1970s Willamette Park was used as a relocation site for fill from the 1969 demolition of the Oregon Journal Building, the removal of Front Avenue, and the excavation of the Vista Ridge Tunnel. In the late 1970s a new state-funded boat ramp and parking lot was built in the park. The fill increased the elevation of the park to its current level and allowed for sports fields to be constructed above the river elevation. It also altered the slope and shape of the riverbank and filled the former shipbuilding yard. The concrete fill and rip-rap can still be clearly seen along the riverbank. The Portland Ship Building Company Aerial of John’s Landing in 1975 - looking south towards covered the majority of the northern portion of the park Willamette Park between SW Nebraska and SW Idaho Avenues and was acquired in 1969, enlarging the park.

There was no official planning for the park until an initial study was completed in 1986. With strong input from the community, the plan sought to encourage a diversity of uses, make the park safer, improve existing facilities and enhance the visual appeal. In 2011, Portland State University Master of Urban & Regional Planning student- led project (Quercus Planning Group) developed the Willamette Park Assessment & Recommendations report which served as a preliminary guide to PP&R as they began to coordinate a variety of improvements to the park.

The prioritization from the a long list of ongoing maintenance projects and issues committee will be used to guide the work of PP&R staff. that need attention. This information formed the basis of Due to the number of projects occurring within and the discussion with the community and the PAC. having the potential to impact the park, the prioritization was general. PP&R committed to keeping the committee The PAC was recruited from throughout the southwest informed as information becomes available as to how community and included constituents who represented work will unfold in the park. the diversity of park users. The committee included adjacent neighbors, boaters, dog walkers, environmental enthusiasts, young parents and the business community. The committee met five times from April through October. The purpose of the Advisory Committee was

“to develop a long-term vision for Willamette Park that incorporates short term developments and opportunities (pump station development and restoration work) with community needs and current and emerging uses. This vision will be used to prioritize the expenditure of compensation funds received from property transfer of parks open space to the Water Bureau for the purpose of building a pump station and other funds as they become available. “

The initial work of the PAC was to focus on understanding the opportunities for programming, recommend a PAC site walk prioritized list of projects and providing feedback on design alternatives. As a starting point, the PAC created the following Guiding Principles: t Balance and integrate environmental restoration and recreational needs t Improve circulation t Minimize user conflicts t Leverage maximum use of resources t Improvements respect parks relationship to neighbors

Related Projects

There are three major projects proposed for the vicinity of Willamette Park, each of which affect park access and use. The Sellwood Bridge replacement project will result in a major re-alignment of the trail corridors south of Willamette Park and direct many more cyclists and pedestrians through the park on the Greenway Trail. The Riverbank Restoration project will reconfigure much of Willamette Park’s riverfront edge. The new pump station will be a large new facility on the west edge of the park, with associated circulation improvements and plantings.

Sellwood Bridge

Planning work to replace the Sellwood Bridge began in 2006. A preferred alternative was selected in 2009. The new steel deck arch bridge will have two 12’ shared Proposed Sellwood Bridge (T. Y. Lin International) use sidewalks, and two 6.5’ bike lanes. The project’s Environmental Impact Study suggests that 7760 cyclists will cross the bridge every weekday (compared with 440 cyclists currently) and 10,620 on weekends (600 currently).

The bike and pedestrian improvements on the new bridge triggered the need to reconfigure the bicycle paths on the west side of the bridge connecting to the Willamette Greenway and Willamette Park. A new regional trail will be constructed alongside the old Willamette Shore Trolley line, and will connect with the south end of SW Miles Place.

Water Bureau Pump Station in Proposed Pump Station (MWA Architects) Willamette Park

After 97 years of service, the Fulton pump station on SW Nevada, between SW Macadam and SW Virginia, needed to be replaced to satisfy future service requirements and fire flows. An extensive public process put the pump station in Willamette Park. The new Hannah Mason Pump Station will feature 4 new restrooms, a new pedestrian plaza, native plantings and an improved park entrance at SW Nevada Street. As compensation for the loss of land, the Water Bureau paid PP&R $655,000. The compensation funds will be used exclusively in Willamette Park.

The PSU Quercus Planning Group project collected information from stakeholder interviews, user surveys and numerous site observations and combined with PP&R assessments, developed an initial list of projects eligible for this compensation funding.

Willamette Park Bank Restoration

The Willamette Park riverbank is a combination of demolition debris and fill that has become overgrown with a mix of native and non-native vegetation. The bank’s gradient is steep and does not allow access to the river and the large rip-rap concrete pieces are unstable.

The City of Portland’s BES is seeking opportunities to improve the natural condition of the Willamette River banks to improve habitat for salmon and other native species. Publicly-owned reaches of the riverbank are particularly desirable as restoration target areas. The Willamette Park portion of the riverbank has been recently restored in certain sections, and given the importance of the in-water salmon habitat in this location, there is interest in completing the restoration of the bank south of the boat ramp and in the northern Existing riverbank overgrown with cottonwood trees part of the park. and non-native vegetation

The Portland Harbor’s Superfund site on the Willamette north of downtown is also eligible to fund restoration work elsewhere on the river in exchange for partial credits towards the required cleanup of the polluted harbor. These conditions make riverbank restoration in Willamette Park particularly attractive in the near future and there are efficiencies that can be gained through coordinating a variety of projects such as the Greenway Trail and new DOLA.

The restoration project is expected to provide the following ecological and recreational benefits: t Enhance river function t Provide refuge for salmon and other native fish species Existing demolition debris and large unstable concrete t Enhance terrestrial and amphibian habitat pieces for native species by improving the riparian and mud flat habitats. t Educate the public about native species and their habitats t Allow access to the river for park users t Extensive revegetation activities are proposed to control invasive species and to enhance emergent, scrub-shrub and riparian wetland plant communities.

Fixed Park Elements

There are several fixed elements that are not considered for improvement in this plan:

t North parking lot t Boat ramp and parking lot t Sports field 1 (drainage and turf improvements may be necessary) t Tennis courts t North play area t Picnic shelter t South parking lot t Sports field 2 (southern field) Park Usage

PP&R keeps track of park usage and reservations of park Existing soccer field facilities, which has been steadily increasing. A summary of usage from 2000-2011 found that the heaviest programmed use of the park is of the two sports fields (#1, next to the boat ramp) and the smaller southern field, #2). These two uses together account for 58% of park reservations and increased dramatically in 2005, perhaps due to soccer leagues being permitted to use the park. The four tennis courts accounted for another 28% of reservations. The picnic shelter comprised much of the remainder.

Story Garden

In 1993, the artist Larry Kirkland and Walker Macy created the Story Garden for Waterfront Park in downtown Portland. The original artwork consisted of a 60’ diameter circular maze, simply constructed of dark gray basalt cobblestone originally used for Portland street pavings. The maze featured 120 carved inlaid granite pieces inscribed with messages, images and quotations. At the south end of the maze, a granite throne on a knoll overlooked the space, while a carved gateway guarded the entrance to the north. The design created an engaging play area without using conventional play equipment. Through the maze, which served as a metaphor for life’s journey, visitors were encouraged to explore their own individual lives.

When the West Side Big Pipe project was constructed Story garden at its former Waterfront Park location in 2003 by BES, the Story Garden was removed, with a commitment from PP&R and BES to re-site the piece at a future date. The former Story Garden site has since been developed as the home for the Portland Saturday Market. With the assistance of the Regional Arts & Culture Council (RACC), PP&R is seeking a new site for the Story Garden.

Urban and Natural Context

Willamette Park is part of a mosaic of natural areas along The west edge of the park is dominated by large office the river that includes Ross Island, Oaks Bottom, Sellwood buildings and parking structures along SW Macadam Riverfront Park, Willamette Moorage Park, and Powers Avenue. The scale of these buildings creates a 4-5 story Marine Park. The park sits at the lowest elevation in the wall, interspersed by surface parking lots which allow California Subwatershed. It helps to infiltrate stormwater views between the buildings into the park. Some office before runoff enters the river, while providing valuable buildings take advantage of their park adjacency, with riparian and bird habitat.

The Willamette Greenway Trail passing through the park is a major thoroughfare for non-motorized transportation. In the future, when the Red Electric Trail is constructed, it will be connected to more SW Portland residents.

Solar and Wind Exposure

The park features large open lawn areas with good solar access. There are few hills to the south that block winter sun. The West Hills do ensure earlier sunsets than other parks in western suburbs. With a riverfront location, the park is more subject to prevailing summer and winter breezes up and down river.

Subsequent filling of the park raised its elevation considerable restrictions on development.

Site Analysis 23 Willamette Park Redevelopment and Phasing Plan

Topography and Drainage

The park is situated about 30’ above sea level (COP Datum). SW Macadam is another 5’-10’ above the park, and buildings on the park’s west edge are built into the slope. A wooded depression on the west side of the main park road, which now serves as a dog off-leash area, is 4’-8’ below the surrounding park’s elevation. In general, the park slopes very gently towards the river, until the concrete riprap bank itself, which in several places is very steep. The area immediately north of the boat ramp is more gently sloping and the river offshore is shallow, exposed at low water as an extensive mudflat.

Stormwater is generally conveyed from inlets west of the park in pipes directly into the river. A new stormwater treatment swale was constructed in 2011 to slow and filter water from the eastern half of the boat ramp parking lot. The parking lot’s other half drains into the wooded depression that forms the park’s western edge. Stormwater from park paths generally drains into surrounding lawn and natural areas, although there are issues with ponding on some park paths. One of the pump station mitigation projects will add small stormwater treatment facilities in the north and south parking lots.

Habitat

Willamette Park includes three habitat areas that provide natural resource benefits. Along the western edge of the park, there is a 2-acre low-lying grove of trees that includes several Oregon White Oaks, city-designated as Merit Trees. The use of the area as a dog off-leash area does not allow for establishment of vegetation below the trees. There is one city Heritage Tree in the park, a large White Oak on the park’s southern edge. This is marked with a plaque along the trail west of this almost 300 year old tree. Development in the park will need to take care to avoid impacts to the tree’s root zone.

The park’s southern riverbank was revegetated in 2009 as part of a broader effort to restore the mouth of Stephens Creek in Willamette Moorage Park to improve salmon habitat. The bank’s angle was lessened, small amount of riprap removed and native vegetation added. A split rail fence prevents access within the restored riparian habitat. A series of stone steps was added to direct public access to the river’s edge.

The area north of the boat ramp has been restored recently, with a new stormwater swale and native plantings. Just offshore from this area, a large mudflat exists at low water, which is important aquatic habitat and a rich feeding area for birds.

Zoning

The park is zoned Open Space (OS), a designation that includes a wide variety of recreational and open space uses. There are three overlay zones in the park, including a Design Overlay (d) that “promotes the conservation, enhancement, and continued vitality of areas of the City with special scenic, architectural, or cultural value” and results in greater scrutiny of proposed development projects through the Design Commission. There are two Greenway Overlay Zones: the entire park is within the River Recreational (r) overlay, which encourages river-dependent and river-related recreational uses with public access to and along the river, and which enhance the river’s natural and scenic qualities. The park south of and including the boat ramp is within the Water Quality (q) overlay, which includes additional provisions to protect the health of the Willamette River including a 50’ Water Quality Setback from the top of the riverbank.

The western and northern boundary of the park are adjacent to property zoned Storefront Commercial (CS) and the southern boundary of the park is adjacent to property zoned Residential (R5) and (R2).

In 1987, the Willamette Greenway Plan was adopted by Portland City Council. This sets a greenway setback of a minimum of 25’ landward from the top of the bank to any development in the park.

Views

The City of Portland’s Willamette Greenway Public Access Map (33.440-1, Map 5) formalizes four view corridors from adjacent neighborhoods into the park and to the Willamette River. These 60’-wide view corridors, at SW Nebraska, SW Vermont, SW California and SW Nevada, have prevented buildings from being built within the corridors. The Greenway Overlay code also denotes a major viewpoint for the park, generally located south of the boat ramp, midway between the SW Vermont and SW California view corridors. As the Overlay Zone code chapter notes:

View corridors provide visual access and connections to the river for neighborhoods and business districts who might otherwise be visually cut off from the river. View corridors are generally extensions of existing public rights-of-way through to the river.

The views from the designated view corridors are impressive, with Mt. Hood visible on clear days and the towers of downtown Portland prominent from the northern part of the park. The river and Ross Island form the foreground to most other park views.

General views from the park’s riverbanks are a very important consideration in this plan and future planning efforts. Riverbank vegetation should be managed to maintain views through certain stretches of riverbank north of the boat ramp and in the southern park.

The Willamette Greenway Trail is one of the key features in Willamette Park and receives high use from pedestrians and cyclists. The trail connects the park to downtown and to the Springwater Corridor by way of the Sellwood Bridge, supporting the City’s growing interconnected trail system. It is projected that once the new Sellwood Bridge opens, the Greenway Trail will be subject to a dramatic increase in use by cyclists and pedestrians.

REDEVELOPMENT PLAN Willamette Park Redevelopment and Phasing Plan

Redevelopment Plan

Through a series of meetings with the PAC, PP&R staff, and a public open house, the concepts were discussed and the redevelopment plan was formulated.

The redevelopment plan for Willamette Park is generally a series of sequenced improvements to preserve and enhance an already popular and well-functioning park. Specific attention is paid to improving the entrances to the park, especially the north and south entries, which will see heavy increases in bike and pedestrian traffic with the addition of a regional trail connecting the Sellwood Bridge to the park. The park’s circulation system will also be enhanced, with new connector trails to create more loop walks. A new trail along the west side of the park will provide access through the oaks and connect to these loops. The existing DOLA will be relocated to the north area of the park adjacent to the SW Nebraska Street entrance and the northern parking lot. Native oak habitat will be restored along the western edge of the park, between the access road and the existing rail line.

On the river’s edge, the restored riverbank will include several improved viewpoints along the Greenway Trail and one new, accessible path down towards the water. The restored bank and plantings will improve the river and riparian habitats. A new launch for non-motorized boats will be provided adjacent to the existing boat ramp, while the existing access steps will remain. In the southern portion of the park, new amenities proposed include a site for the Story Garden adjacent to the parking lot, circulation improvements associated with the new pump station and a new location for the SW Miles Place play area.

Park Entries: North

The existing north entry is an old road, closed with a set of rusting bollards. Portions of this road are also used by the sailing club. The plan proposes a more formal entry to the park that informs users that they are on the Greenway Trail by marking the entry and narrowing the existing roadway to the 10’ Greenway Trail width. Where the trail crosses the parking lot access road there will be a raised crosswalk to slow cars and provide preference to cyclists and pedestrians.

At the SW Nebraska park entrance, several improvements are proposed. The old raised island in the roadway which once housed a fee collection booth will be removed. Currently there is only a sidewalk connecting into the park on the north side of the park. A new walk will be added to the south side, extending the sidewalk that ends at the railroad tracks. The track crossing will also be improved for accessibility. A new sign will be placed at this entry, replacing the old wooden monument. At the site of this monument, the road will be narrowed, removing an old bump-out to the east. New landscape plantings at the end of SW Nebraska will help screen the DOLA beyond.

Park Entries: Pump Station

The new pump station design includes a number of improvements to the informal entry to the park from SW Nevada Street. New rail crossing walks will be added and the trail into the park re-routed to join the southern loop trail. A plaza around the pump station will include seating, bike racks, a drinking fountain and restrooms.

Park Entries: South

A new plaza with signage will guide commuter cyclists to the west and pedestrians and slower cyclists to the east, along the Greenway Trail. New seating on this plaza will serve as a rest stop for trail users as well as a neighborhood gathering place. A new sign welcoming visitors to the park will also be added. These changes will be done with the intention of addressing the increasing cycling and pedestrian use resulting from Greenway Trail improvements.

Proposed Trail System

There will be a clear hierarchy of trails at Willamette Park, which will help to separate users and avoid conflicts, while ensuring straightforward wayfinding for park visitors. The Willamette Greenway Trail, currently an 8’ wide asphalt path that winds along the east edge, interrupted by the boat ramp, will be improved and widened to 10’. The new trail location will be coordinated with the bank restoration design, so in places it will be slightly west of its current alignment. It will be connected by short spur trails to the viewpoints and overlooks that are spaced regularly along the riverbank. At the boat ramp, the existing striped crosswalk will be replaced with a raised walk to ensure greater safety for trail users as they cross the busy ramp.

The plan guides commuter bike traffic away from the Greenway Trail. As cyclists enter the south end of the park at the SW Miles Place, they will be directed to the west along a new, wider trail adjacent to Sports Field #2. The existing 6’-wide asphalt path will be widened to 10’, with a soft-surface 2’ track parallel for pedestrians. The new path alignment will need to avoid the root zone of the Heritage White Oak at the south end of the park. Once cyclists reach the pump station, they will cross a plaza and enter the main park road which is a direct route through the park. The road sees considerable auto traffic at times, so ‘sharrow’ markings will be added to the road to indicate that this is a shared space. Cyclists will rejoin the Greenway Trail at the north end of the park.

There are two new hard surface loop trails proposed in the park. The popular southern loop trail will be repaired and will include a portion of the Greenway Trail as well as the new commuter bike trail. A new northern loop will be added around the DOLA, running along the park road and through the trees north of the boat ramp, then joining the Greenway Trail. Adding to this option, a new connecting trail will cross the park between Sports Field #1 and the tennis courts, connecting the Greenway Trail with the main park road. A new soft surface trail through the oak grove is proposed. The soft-surface trails will be for slower, more contemplative walking, away from the bustle of the other park trails.

Habitat Improvements

Bank Restoration

The primary goals of the Willamette Park Bank Restoration Project are to improve riverbank and near- shore habitat conditions, including riparian, beach, floodplain, and shallow-water habitat for the benefit of fish, wildlife and people.

The planning concepts for Willamette Park’s physical improvements were coordinated with initial concepts for the bank layback, adjusting the extent of bank re- grading to minimize impacts to passive open space while providing new public access down to the water’s edge and a series of overlooks that include picnic tables and/or benches. As the layback project proceeds into more detailed engineering design, views of the river and downtown Portland will be protected through careful vegetation management in bank areas below Example of shallow water habitat for native fish and the overlooks and other identified view corridors. amphibian species

Oak Habitat

The western edge of the park between SW Nebraska St. and the proposed pump station will be restored to native Oak habitat. The poor drainage and stormwater runoff will be managed and the understory of the existing Oregon White Oaks will be planted with native shrubs and grasses that do not require routine mowing. The proposed soft surface trail will meander through the restored habitat.

Overlooks

Since the re-grading of the park in the 1970s, the riverbank’s vegetation has matured to the point where a park user’s visual access to the river is often blocked. With the bank restoration project, there is an opportunity to re-open view corridors and re-connect park users with dramatic views of the river, Ross Island and downtown Portland.

The 1988 Willamette Greenway Plan included design guidelines for the creation of river viewpoints:

Viewpoints should be designed as safe, comfortable resting places to view the river. Each viewpoint should be relatively small in size and have a hard surface. It is preferable to design the space using an identifiable Precedent overlook platform (Cape Disappointment SP, WA) configuration, such as a square or semi-circle. In addition, vegetation can be used to shape and define the viewpoint, provide a sense of enclosure, and to frame a view. Well-defined edges help to identify these places and make them more attractive.

Facilities. Each viewpoint should be provided with seating. Consideration should also be given to providing other equipment to facilitate short duration stops, such as ornamental and drinking fountains, garbage containers, interpretive signs, kiosks, and the provision of public art.

Access to Water’s Edge. Where site topography and conservation and enhancement of natural riverbank and riparian habitat allow, viewpoints located adjacent to the river should provide for pedestrian access to the river. Figure 23 - Overlook at SW California view corridor Relationship to Trail. Viewpoints developed in conjunction with the trail should be adjacent to the trail but designed to create a separate identity. It is preferable to locate viewpoints between the trail and s wsw e the river. ViewsVVieVi

Northern In addition to protecting a clear view down the public Overlook right of way and preventing buildings from blocking the views, the 1988 Greenway Plan’s design guidelines Willamette Greenway Trail Bank also note that landscape treatments within view Restoration corridors “should frame and enhance the view of the river”, which should inform future planting plans ViewsVViewews related to the riverbank layback project. DOLA

Figure 24 - North overlook enlargement 030 60ft N

56 Redevelopment Plan Willamette Park Redevelopment and Phasing Plan

Non-motorized Boat Ramp There are three types of overlooks proposed. The largest, to be located in the north end of the park, will be located to take advantage of views to downtown Portland and Ross Island. It will also allow people to view activity at Views the sailing club docks north of the park. This overlook is envisioned as a deck extending over the bank edge, with a solid wall on the bank (i.e., not open underneath). The Overlooks with drop-off to the bank will be less than 30”, so no railing Picnic Tables will be required, although a curb edge is recommended, to prevent wheelchairs and bikes from rolling off the Views edge. Benches will line the edge of the overlook that is adjacent to the Greenway Trail. As shown in Figure 26, vegetation should be managed below the overlook to ensure that the view does not eventually get blocked. There will be landscape between the overlook and the DOLA.

Further south along the Greenway Trail, south of the boat Views ramp, small platforms will be placed, with picnic tables and/or benches, for small groups to gather adjacent to the river.

Another overlook will be located at the end of the SW Bank Restoration California view corridor. This overlook concept presents a semi-circular form, with concrete or stone seat walls. Views This overlook, in addition to being a resting place along the Greenway, will also have an opening for a trail, which River Access Trail will lead down the riverbank at an accessible grade to bring people closer to the water’s edge.

Dog Off-leash Area (DOLA)

The Plan proposes to move the DOLA to the north end of the park. The location is flat and well-drained, has good visibility and is located in close proximity to the existing northern parking lot. The new DOLA will have fewer trees and will be a more useable space for throwing. The new space is smaller than the existing area, but will be an improved facility. The concept plan proposes that this new DOLA will be fenced with a split-rail, wire mesh standard. On the western side of the DOLA, at the end of SW Nebraska Street, a landscape pocket will screen the fence from visitors arriving at the park. Two gates are proposed, at the north and southwest entrances of the DOLA. New shade trees will be planted. The edge adjacent to the proposed viewpoint will also be landscaped to lessen the visual impacts on park visitors.
